Easy to tighten tight band

The present invention relates to a tightening strap, and more particularly to a tightening strap that can be easily tightened.

Conventional tightening straps are commonly used to snap into a buckled component that can be worn by a user (eg, a respirator, medical harness, sports glasses, frog mirror, work cap, hard hat, etc.). However, after the above-mentioned snap-fit is worn by the user and tightened by the conventional tightening strap, it is generally less convenient and quick to adjust when the elastic band needs to be adjusted. Therefore, it is necessary to seek a solution.

Accordingly, it is an object of the present invention to provide a tightening strap that can be easily tightened.

Therefore, the present invention can be easily tightened and fastened, and is suitable for being fastened to a buckled product that can be worn by a user, and includes a first tightening unit and a second same as the first tightening unit. The tightening unit, wherein the first tightening unit and the second tightening unit are all made of an elastic material, and each comprises a rack portion, a fastening portion, and a wearing portion. The rack portion includes an elongated body having a main surface, a sub-surface opposite to the main surface, a fastening end and a piercing end opposite to the fastening end, and a plurality of spaced apart A toothed bump extending outwardly from the major surface of the elongated body. The fastening portion is disposed at the fastening end of the elongated body of the rack portion, and is configured to be detachably fastened to the buckled compound. The insertion portion includes an extending piece extending outward from the through end of the elongated body of the rack portion, and two extending perpendicularly outward from the two side edges of the extending piece and extending in a direction a connecting wall having the same extending direction as the toothed bumps, and a parallel piece spaced from the extending piece by being connected to the connecting walls, wherein the extending piece, the connecting wall and The parallel sheets together define a channel. When the first tightening unit is combined with the second tightening unit, the fastening portion of the first tightening unit is adjacent to the wearing portion of the second tightening unit and the second tightening unit is fastened. The first tightening unit and the first portion of the first tightening unit are adjacent to the toothed protrusion of the first tightening unit and the toothed bump of the second tightening unit The two tightening units are symmetrically placed, and the engaging portion of the first tightening unit is penetrated through the passage of the second tightening unit from the inner and outer directions, and the engaging portion of the second tightening unit is inwardly directed The outer direction penetrates the passage of the first tightening unit, and then the rack portion of the first tightening unit slides in the passage of the second tightening unit, and the rack portion of the second tightening unit is made Sliding within the passage of the first tightening unit.
